"When you feel weak, when you feel sad, I want you to think about Steve's smile," school board president Matt O'Grady told the crowd, many of whom were students. "Think about words of wisdom... encouragement that he shared with you along the way,"

Mayer, 52, was out jogging with his dog, Dutch, near his home at 6:15 a.m. Tuesday when both were struck and killed on Robbinsville Edinburg Road near Anderson Lane in Robbinsville Township.

Sources tell Action News the accident happened as the driver, a female student at Robbinsville High School, was heading to school early for a class trip.

For some students and former students, the loss was emotionally tough.

"He was a great guy to be around with, and that's all I have to say," said former student Alex Buzgo.

"He always saw the children first, and as you can tell by this crowd that is here, he had so much love for this community. It's a loss for our community," said Councilwoman Chris Ciaccio.

Mayer lived in Robbinsville with his wife, a teacher in the Robbinsville schools, and their children.

He was a principal in the nearby West Windsor-Plainsboro Regional School District before he was hired as the superintendent in Robbinsville.

"Steve was an incredible part of our community," said Mayor Fried. "He was our superintendent, he was a coach, he lived here, and he was a friend.... I think the whole community needs a time to mourn. I'm trying right now to be strong as mayor, but I intend to go home shortly and have a good cry for my friend."

"In honor of Dr. Mayer, we will find our way back to normal, as appropriately as possible," said Robbinsville School Board President Matthew O'Grady. "Steve always put the students' needs first, and we will continue that as we work through this devastating loss."

Grief counselors were brought to the high school to speak with staff and students.

"Whether he was making an event better, or just seeing him around, he was always such a nice, loving man. He will never be forgotten," said student Jeremy Wall.

Mayer's passing was announced Tuesday morning in an email message from the school board to parents:
